We regret that the value of serum CRP was reported incorrectly. Serum CRP levels were reported incorrectly to be 10 times higher than their true value. The value of serum CRP in osteoarthritis patients following total knee arthroplasty should have been reported in milligrams per litre (mg/l), instead of milligrams per decilitre (mg/dl) for the whole article. The authors apologise for this error.
